Punch faucet



' Aug. 21, 1934. w. G. sTocKMAN PUNCH FAUC ET Filed Oct. 16, 1933 Walter G. 560 c/iwzan mj wra ATTORNEY Patented Aug. 21, 1934 UNITED STATES PATENT OFFICE My'invention relates to improvement in punch faucets, so called, forv use in connection with fluid containing cans to discharge the fluid therefrom.

The primary object of my invention is to provide a device of this character which is adapted to easily puncture the top of a can, is equipped to effectively seal the puncture against leakage, and which may be securely locked in place on the can top against displacement or readily removed therefrom. as desired.

Other objects, such aslow cost of manufacture and durability, will appear when the following description and claim are read with reference to the drawing accompanying and forming part of this specification.

In said drawing:

Fig. 1 is a. vertical sectional view illustrating the application of a preferred form of my novel faucet to the top of a can.

Fig. 2 is a view in rear elevation with a part of the can top shown in section.

Fig. 3 is a view in front elevation also showing a part of the can top in .section.

Fig. 4 is a fragmentary view, partly in" side elevation and partly in section, showing a modified form of the invention; and

Fig. 5 is a fragmentary sectional view taken on the line 5-5 of Fig. 4.

Referring now to the drawing by numeral, my novel faucet includes preferably a single piece tubular body portion 1 adapted to be inserted into the top 2 of a can 3 in an upright position, and having at its upper end a laterally projecting outlet nozzle 4 and a diametrically opposed air inlet device which in one form of the invention is a laterally projecting nipple 5. The body portion 1 is divided by a vertical partition 1a extending from the upper end thereof substantially half way down said portion and dividing the interior of the faucet into fluid outlet and air inlet channels 117 and 1c communicating with the fluid outlet nozzle 4 and inlet device or nipple 5, respectively. Preferably the air inlet channel 1c is smaller than the fluid outlet channel 1b to provide for a maximum flow of the fluid from the faucet. The lower end of the body portion 1 is beveled to provide a sharp spade-like point 6 and opposed cutting edges '7 and 8 converging to a point of intersection above said point, whereby a substantially circular opening is cut in the top 2 of the can 3.

Substantially midway of its ends the body portion 1. is provided with a laterally extending flange 9 and a resilient gasket 10, the upper side of which seatsagainst said flange. the lower side being designed to seat against the can top, as shown in Figs. 1 to 4, inclusive. A pair of diametrically opposed fins 11 are provided on said body portion, said fins having top edges 12 disposed below the gasket 10, so that when the faucet is inserted in the can top 2 with the gas-. ket 1O slightly compressed, said upper edges 12 will engage the underside of the can top 2 and preventdisplacement of said faucet. Preferably the flns 11 are struck up from the body portion 1 and the upper edges 12 and side edges 13 form obtuse angles, so thatthe edges 12 incline upwardly toward said body portion and the edges 13 incline inwardly toward said body portion for a purpose presently clear.

In the use of my novel faucet the sharp Y spade-like point 6 is forced thru the can top 2, the before-described cutting edges '7 and 8 cutting a circular piece from said top, the cutting being progressive as will be clear. The faucet is forced thru the can top 2 until the resilient gasket 10 contacts said top and is slightly compressed. During this operation the fins 11 are forced thru the can top, forming slots 14 therein, this operation being facilitated by the angular edges 13 of said fins, as will be clear. A slight turn is next imparted to the faucet to move the fins 11 out of alignment with the slots 14, Whereupon their upper edges 12 contact the underside of the top 2 of the can, thus securing the faucet against displacement. By tilting the can the contents thereof may be readily expelledand the flow regulated by closing or opening the end of the nipple 5 with the thumb or finger. When it is desired to remove the faucet, it is turned until the fins 12 register with the slots 14, whereupon it may be readily withdrawn. As an optional method of removal sufli cient force may be applied to pull the fins thru the top 2 of the can without turning the faucet, the angular edges 12 acting as cutting edges.

In Figs. 4 and 5 a modified form of the invention has been shown in which a single valve isutilized to regulate the outflow of the fluid and also the inlet of air. prises a cylindrical portion 16 rotatably mounted in a nipple 17 and the partition let for operation by hand grip member 18. The inner end of the portion 16 is bifurcated as at 19 so that when said valve is turned with said bifurcation 19 in vertical position fluid is free to pass thru the outlet channel 1b, and when said valve is turned with the bifurcation 19 in transverse po- The valve 15 comsition the faucet is closed. An air inlet port 20 I extends thru the hand grip member 18 into communication with the air inlet channel 10 of the faucet, as shown in Fig. 4, said port 20 having a portion 21 parallel with the bifurcation 19 so that when the valve is in faucet opening position airwill be admitted to the interior of the latter andwhen said valve is in faucet closing position-said port 21 is closed.

The foregoing constitutes adetailed description of a preferred embodiment of my invention and one modification thereof but it is to be understood that right is herein reserved to other modifications of the invention and changes therein falling fairly within the scope of the protection prayed.

What is claimed as new is:

A punch faucet for use with liquid containing cans and including, a tubular body portion one end of which is pointed for puncturing the can and having at its upper end a laterally projecting liquid outlet nozzle and an air inlet nipple diametrically opposed to said nozzle, and a partition dividing the body portion into liquid outlet and air inlet channels communicating with said nozzle and nipple respectively, said inlet nipple being designed to be opened and closed or partially so by the thumb or finger of the operator for the purpose of controlling the flow of liquid thru said outlet nozzle and being opposed to the latter for convenience in opening and closing.
